CAR-ROOF.

Application led May 5, 1913. Serial No. 765,511.

Allegheny and State of Pennsylvania, have.

invented a new and useful Improvement in Car-Roofs, of which the following is a specification. y

This invention relates to car roofs, and more particularly to Outside metal roofs comprising movably mounted transversely extending sheets which are connected at their side margins by flexible or loose waterproof seams.

It has for its principal objects to provide improved securing means for the end sheets; to provide for limited movement of the sheets endwise and sidewise and yet prevent leakage under them; and to attain certain advantages which will hereinafter more fully appear. I

The invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings, which form part of this specification, and wherein like symbols refer to like parts wherever they occur,-Figure l is a top plan View of the end portion of the car roof illustrating an embodiment of theinvention; Fig. 2 is an end elevation; Fig. 3 is a vertical longitudinal section through the roof in the region of the ridge; Fig. 4 is a vertical longitudinal section through the roof on the line 4-4 of Fig. 2; Fig. 5 is a section through the retaining cap detached, said section being taken where a corrugation occurs; Fig. 6 is a fragmentary end elevation of the roof in the region of the ridge; Fig. 7 isa fragmentary side elevation of one of the retaining cap sections detached, showing the eaves end arrangement of the cap before it is applied on the car; Fig. 8 is a fragmentary side elevation of the cooperating retaining cap section, the eaves end portion being shown as applied to the car; and Fig. 9 is a fragmentary end view of the retainincap.

he roof shown in the drawings 1s of the hip type. That is, the roof inolines downward to the eaves on opposite sides of the middle ridge. The roof sheets 1 extend transversely of the car from the ridge to the eaves; said sheets being respectively Joined by raised seams 2 at the ridge, and by similar seams 3 at their side margins. The

sheets may be secured at the eaves by the y usual hood castings 4 which loosely straddle the side seams 8, or they may be secured in any other desirable manner.

The roof substructure shown in the drawings comprises wooden sheathing 5 which is nailed to the longitudinal and transverse frame members; but as far as the present invention is concerned, the substructure may be of any suitable or desirable construcn The outer side marginal portions of the end roof sheets 1 are turned down, as at 6, into recesses or rabbets 7 in the end fascia 8 or in the end sheathing of the car, as the case may be. Elongated retaining members or caps 9 of angle section, and preferably made of sheet metal, are secured to the end fascia 8 so as to overhang the end sheets. As shown, there are two of the end caps, each extendingfrom the middle of the car to the eaves. They are secured at intervals throughout their length by nails 10 which are preferably driven into the end plate 11 except where the end plate is gained to receive the end of the ridge pole 12, at whichy place the nails are driven into the end of the ridge pole.- The retaining caps are further secured by bolts 13 which extend entirely through the end plate; and it is preferable to provide angle clips 14 at the places where the bolts 13 are used, said clips being perforated for the passage of the bolts therethrough. The clips 14 thus serve as reinforcing washers under the bolt heads and also reinforce the inturned portions -Of the ca'ps which overhang the end sheets. The meeting inner end portions of the retaining caps are made to overlap eachother and they are respectively provided with' hood portions Qaand 9b adapted to straddle the ridge seam 2 which connects the adjacent end sheets. The caps are also corrugated transversely, both on their downturned and inturned portions, as at 15, 16, said corrugations respectively merging at the corners of the caps. These corrugations stiften the caps transversely, and those in the downturned portions of the caps further provide an outlet for water and cinders or any other substance which might work between the caps and end sheets into the rabbet 7.

The retaining caps are slitted or cut away" at their corners for some distance inward from their outer ends so as to provide tongues 17 and 18 which are respectively continuations of the downturned and overhan ging portions of the caps. In applying the caps, the tongue portions 17 are bent inward against the side of the car, and the portions 18 are bent down over the eaves, overlapping the inturned portions 17. These tongue port-ions are secured by nails which are driven into the side of the car, perforations 1 9, 20, being preferably provided in said tongues so' as to register when the tongues are folded ready to be fastened. The retaining caps may be made in more than two sections, if desired, or they-may be made in .one piece so as to extend continuously from side to side of the car; and said caps, par ticularly in the latter case, serve as a tieplate and reinforcement for the end of the i' `car in addition to holding down the roof sheets. 4

Obviously, the structure admits of considerable modication without departing from the invention. Therefore, I do not wish to be limited to the exact construction and arrangement shown.

What l claim is:

l. In a car roof, the combination with two coperating V,end sheets, said sheets extending transversely of the car and being connected at the ridge by an upstanding seam, of two cooperating angle shape retaining members'fastened to the end of the car and having one of their fianges overhanging the adjacent marginal portions of the respective end sheets, said retaining members extending from the ridge to the eaves, the inner end portions of said retaining members being overlapped and provided with hood pori tions straddling the ridge seam of said end` tions straddling the ridge seam of said end sheets, and the outer end portions of said retaining members being turned against the sides of the car and fastened thereto.

3. 1n a car roof, the combination with two cooperating end sheets, said sheets being movably mounted on the substructure, said sheets extending transversely of the car and being connected at the ridge by an upstanding seam, the end of the car having a rabbet into which the outer side marginal portions of said sheets are turned down, of an elongated angle shape end flashing and retaining member one of whose flanges is secured to the end of the car below said rabbet, its other flange being disposed inwardly so as to overhang and bear loosely upon the adjacent end sheet,'said overhanging flange extending continuously from ridge to eaves and turned down at the eaves i end and having a hood portion at the ridge end adapted to straddle and cover over the end of the ridge seam of the end sheets.
